GRAPEVINE (CBSDFW.COM) - Popping the cork off a bottle of champagne, employees at the British Emporium in Grapevine offered plastic cups to customers wishing to toast the new prince.

The birth of a son for Prince William and Kate Middleton was cause for celebration there. The owner of the British goods store, Sheela Kadam says, baby fever’s been good for business.

“Everyone has been for the last week talking about the royal baby,” says Kadam. “We’ve seen an uptick in business and a great interest in all things royal.”

The store is even running a contest to see who can guess the baby’s name.

“We have quite a few George’s in here… Edward, there’s an Edward here,” she said, flipping through entries.

Playing on that public interest, Pizza Hut made its own announcement to coincide with the birth.

In a nod to the royal tradition at Buckingham Palace, an intern dressed as a royal guard stood watch over an easel with news of a “royal offer” outside the company headquarters.

“Our bundle of joy that we’re giving to all of our fans here in the US is a free side item – cheese sticks, bread sticks…,” said Doug Terfehr, Pizza Hut’s director of public relations. (To claim – use the code “royal offer” when you buy a pizza online through this Thursday.)

At Baylor Regional Medical Center at Grapevine, Trisha Thievon is thrilled at her own arrival, born within hours of the royal baby.

“We have our royal little prince,” she said,

Thievon admits she followed the news of Middleton’s pregnancy, but said the day is even more special for another reason.

It’s the same day she gave birth to twins, four years ago.

“I was hoping he would come today, so they would share the same birthday,” she said.
